Q.(a) Write a Python function that displays all the lines containing the word 'vote' from a text file "Elections.txt". For example, if the file contains : In an election many people vote to choose their representative. The candidate getting the maximum share of votes stands elected. Normally, one person has to vote once. The process of voting may vary with time and region. Then the output should be : In an election many people vote to choose their representative. Normally, one person has to vote once.

Part (a)

Read the file line by line and print a line only if the word vote occurs in it. The expected output excludes the "share of votes" line and the "voting" line, so we must match the whole word vote, not just the substring — done by splitting each line into words and stripping punctuation.

def display_vote_lines():
    with open("Elections.txt", "r") as f:
        for line in f:
            words = [w.strip('.,!?;:').lower() for w in line.split()]
            if 'vote' in words:
                print(line.strip())

For the sample file, expected output:

In an election many people vote to choose their representative.
Normally, one person has to vote once. …

Part (a)

The task is line filtering. Open Elections.txt in read mode, iterate line by line, and decide whether to print each line.

The key subtlety is in the sample: the second line ("... maximum share of votes ...") and the fourth line ("... process of voting ...") are NOT in the expected output, even though both contain the substring vote. So we must test for the whole word vote, not the substring. We do this by splitting the line into words with split(), stripping punctuation from each word, lowercasing, and checking membership.

def display_vote_lines():
    with open("Elections.txt", "r") as f:
        for line in f:
            words = [w.strip('.,!?;:').lower() for w in line.split()]
            if 'vote' in words:
                print(line.strip())

Trace on the sample:

• Line 1: words include vote -> printed.
• Line 2: word is votes (not vote) -> skipped.
• Line 3: words include vote -> printed.
• Line 4: word is voting (not vote) -> skipped.

Expected output:

In an election many people vote to choose their representative.
Normally, one person has to vote once. …
